Abstract

Demographic characteristics and clinical data of all newly diagnosed biliary atresia patients in Shanghai were collected from 1 January 2015 to 31 October 2016. The total number of live births was 377 420 during the study period, and the incidence of biliary atresia in Shanghai was 10.86 per 100 000 (95% CI 7.8 to 17.74), with 62.9% and 45.7% cases retaining native liver survival at 2 and 5 years after Kasai procedure, respectively. Implementation of systematic screening measures for biliary atresia in China is needed.
